It should be a real screamer if it is as hot as the
NOSLER 115 grain load at:
1550fps / 614 ft. lbs. 4"bbl

3.5" barrel - 1494fps
4.5" barrel - 1612fps

That load exhibits some muzzle flash, but a lot of bang.
Noticeably- faster than the 125s and 147s/

Note, that like Nosler load, the once again available DT 115 gr.
uses a flash supressed powder for virtually no muzzle flash
as well.

Both should remain the fastest in the DT .357 SIG line,
except for the DT 80 gr. Barnes TAC-XP:

1725fps / 529 ft. lbs. 4.25"

3.5" barrel - 1600fps
4.5" barrel - 1755fps

( the load I carry in my RAMI P)

And have some appeal to those looking for truly smoking hot
.357 SIG ammo.
